At baseline, patients will be asked to fill quality of life questionnaires (EQ-5D, AVVQ and CIVIQ) and will have their clinical scores assessed (CEAP and VCSS). On discharge after their varicose vein intervention, they will then be provided with a diary to record their post-procedural pain every day for 10 days using a validated visual analogue scale (VAS) as well as to record when they return to their normal activities and are back to work. They will also be asked to attend a follow-up in 2 weeks and at 6 months.
